The griffon vulture (Gyps fulvus) is a large Old World vulture in the bird of prey family Accipitridae. It is also known as the Eurasian griffon. Like other vultures, it is a scavenger, feeding mostly from carcasses of dead animals which it finds by soaring over open areas, often moving in flocks. It establishes nesting colonies in cliffs that are undisturbed by humans while coverage of open areas and availability of dead animals within dozens of kilometres of these cliffs is high.[4][5] It grunts and hisses at roosts or when feeding on carrion.
